From the companies house document it confirms 4 people have Owner Shares , John Allot , Michael Carter, Roger Lambert ( no longer a director according to Companies House ) and John Minards.
I presume that Owner Shares come with voting rights. Then there is listed the people who recently very generously purchased Member Shares, I presume these shares do not have voting rights. At the bottom of the list of people who own member shares is shows Frank Carter who with amazing generosity purchased 300,000 member shares, top man. It does not indicate when these were purchased, it is again a presumption that they were purchased at roughly the same time as the several other people bought mainly 500 or 1000 member shares each. Not including Frank Carter the total Member shares sold was 49,500.
So trying to get to grips with all the informed gossip it would seem that to take control of the club a potential buyer would need the 4 people who have the Owner shares to agree to sell them, it can of course be at a nominal figure as I presume that they have no value, especially as Sports Clubs tend to have considerable debt. So unless there is something in the constitution that says that if a majority of Owner shares vote to sell then a sale goes through. I suppose it could be anyone of the Owner Shareholders who believes its not a good idea to sell to any particular buyer.
